Density functional theory calculations were carried out on the structurally characterized [(Cl4-cat)Mo(py)Fe3S3(CO)4(PnPr3)3],A, and (Cl4-cat)Mo(py)Fe3S3(CO)6(PEt3)2,B, and also onA2-andB2+clusters. The Fe−Fe distances in these molecules depend on the total number of valence electrons (60 e-inAandB2+and 62 e-inA2-andB) and undergo great structural changes upon addition or removal of electrons. The changes are consistent with known electron-counting rules in organometallic chemistry. The weak nature of the Fe−Fe bonding interactions in these clusters is apparent in the very similar energies of states with widely different Fe−Fe distances.
